Introduction:
Bacterial meningitis is associated with a high mortality and a high incidence of neurological sequelae. Parainfectious vasculitis leading to ischemic brain damage is a known complication of bacterial meningitis but its treatment is uncertain.
Methods And Results:
We report the case of a 53-year-old man with pneumococcal meningitis who developed numerous ischemic lesions in the brainstem and basal ganglia caused by parainfectious vasculitis. Clinical and radiological improvement was observed after delayed corticosteroid initiation. Symptomatic vasculitis relapsed after steroid withdrawal and stabilized after reintroduction of the immunosuppressive therapy. Although the cerebrospinal fluid (CSF) contained high levels of MMP-9 at the time of symptomatic vasculitis, a significant decrease of the enzyme accompanied the introduction of corticotherapy and the regression of vasculitic symptoms. No relation between the level of MMP-9 and the white blood cell count in CSF could be found.
Conclusion:
Parainfectious vasculitis may respond to late corticosteroid treatment. MMP-9 level in CSF may be a marker of vasculitic complication in bacterial meningitis.
Insights
Late corticosteroid treatment may improve outcomes for bacterial meningitis patients with parainfectious vasculitis. Cerebrospinal fluid matrix metalloproteinase-9 (MMP-9) levels may indicate this serious complication.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Bacterial meningitis presents significant mortality and neurological sequelae risks.
- Parainfectious vasculitis is a recognized complication leading to ischemic brain damage, yet treatment remains unclear.
Observation:
- A 53-year-old male with pneumococcal meningitis developed extensive ischemic lesions in the brainstem and basal ganglia due to vasculitis.
- Clinical and radiological improvements were noted following delayed corticosteroid administration.
- Vasculitis recurred upon steroid cessation, stabilizing with immunosuppressive therapy reintroduction.
Findings:
- High cerebrospinal fluid (CSF) matrix metalloproteinase-9 (MMP-9) levels correlated with symptomatic vasculitis.
- MMP-9 levels decreased significantly with corticotherapy and vasculitic symptom regression.
- No correlation was found between CSF MMP-9 levels and white blood cell counts.
Implications:
- Late corticosteroid therapy can be effective for parainfectious vasculitis in bacterial meningitis.
- CSF MMP-9 may serve as a valuable biomarker for detecting vasculitic complications in bacterial meningitis.
